1 represents the main frame of the machine which may be of any suitable construction so as to support the working parts of the machine.

2, Figures 2, 7 9, and 18, represents a number of main dials which register the total of the numbers which are added together. These dials consist preferably of cup-shaped wheels which are numbered on their peripheries and are mounted in their proper order on a transverse dial shaft 3, which is journal'ed in bearings on the main frame, the dials being so arranged that the dial representing the lowest number is arranged on the right hand end of the series and the dials representing the successively higher numbers being arranged successively in their order toward the left from the dial representing the lowest number. The lowest or right hand dial is preferably divided on its periphery into one eighths so as to indicate fractions of a cent in III , wardly mas-m eighths, and the remaining dials are graduated on their periphery accordin to the decimal system into tenths. As s own in the drawings ten of these dials are shown and extend from fractions of a cent to tens of millions, but if desired, additional dials may be added to the right and to the left of the series, if it is desired to register smaller divisions of a cent or more than tens of millions. Each of the dials 2 is provided on its lefthand side with a gear pinion 4, which is rigidly connected therewith, as shown in Figures 2, 7, 9, and 18.

The pinion of the fraction wheel has eight teeth while the inions of the remaining dials are each provi ed with ten teeth. 5 represents the main registering gear segments, one of which is provided for each of the dials 2 and is adapted to engage with the pin on thereof, for operating the respective dlal. Each of these gear segments is arranged in rear of its companion gear pinion and is provided at its lower end with a rearwardly projecting arm 6 which is pivoted loosely on a transverse supporting rod 7 This rod 18 mounted with its ends on the upper ends of two rock arms 8 which turn loosely with their lower ends on a transverse rock-shaft 9. The rock-arms 8 are connected by a transverse bar 10 which compels the two arms to move back and forth together. In the normal position of the gear segments when the machine is at rest these segments are retracted rearout of engagement from the dlal pinion of the dials and the segments are elevated so that their lowermost teeth are opposite the spaces between the ad'acent teeth of the dial pinions, these spaces sing in line with the pivots of the piriions and the gear segments.

The gear segments are yieldingly held backwardly out o enq'agementwith the dial pinions bymeans of springs 11 (Fig. 14) con? necting the rock-arms 8 with a stationary part of the frame. Figure 14 shows one of the springs 11 connecting one of the roclr-arms 8 with a transverse stationary bar 12 in the rear part ofithe machine. The gear segments are moved forwardly so that thelr teeth engage with the dial pinion 4, by means of a shifting rock-arm 13, WhlCh is preferably secured to the right hand roclt-arm 8 and projects rearwardly. Upon raising the shiftlng rock-arm 13, the rock-arms 8 are swung forwardly and the gear segments 5 are engaged with the dial pinions, whileupon swinging the shifting rock-arms downwardly, the rockarms 8 are swung rearwardly and the gear segments are disengaged from the dial pinions.

14 represents a cam whereby the gear segments are engaged with the dial pinions. This cam is mounted on the upper portion of I a vertically swinging rocking frame 15 which is arran ed on the right hand side of the machine. his cam is provided at its front end -with-an inclineor camface16 and at its rear end with a concentric face .17. When the cam is in its rearmost or retracted position, its

incline stands in rear of a rolleg or projection 18 on the rear end of the shifting arm 13, as shown in Figures'2, 7, 9, and 19. Upon swinging the rocking frame 15, so that the cam 14 moves forwardly, the incline of the latter engages underneath the roller 18 and raises the arm 13, thereby moving the arms 8 forwardly. The throw of the incline 16 is just suflicient to engage the teeth of the gear segments with the dial pinions. When the roller 18 has been raised to the top of the incline, the concentric portion of the cam engages with the roller during the continued forward movement of the cam and the latter does not shift the gear segments any further forward.

When the rear end of the concentric face 1'? of the cam passes forwardly from underneath the roller 18, the constant pull of the springs 11 causes the rock-arm 13 to be depressed and the rock-arms 8 to be moved rearward, thereby disengaging the gear segments from the dial pinions. Upon now moving the cam 14 backwardly together with the rocking frame 15, this cam does not afiect the arm 13 and the parts connected therewith, but is affected by said arm at the last portion of the backward movement of the cam, at which time the back or lower side of incline 16 engages with the roller 18, which lifts said incline and at the end of the backward movement of the cam, the latter clears said roller and drops behind the same, as shown in Figure 2, preparatory to again raising the roller 18 and connecting parts during the next forward movement of the cam 14.

For the purpose of permitting the front end of the cam to rise so as to clear the roller 18, this cam is pivoted at its rear end to the rear portion of the rocking frame 15. The upward and downward movement of the front end of the cam is limited by means of a lug 19 projecting from the side of thecam and engaging with a slot in the adjacent part of the rocking frame 15, as shown in Figures 19 and 36.

The rocking frame 15, is secured with its lower portion to a transverse rock-shaft 2O journaled in the main frame and provided outside of the frame with a hand crank 21, as shown in Figure 19, whereby this shaft is rocked and the parts connected therewith are operated.

The gear segments 5 are raised to their highest position by means of a return or lifting bar 22 which extends transversely underneath all of the arms 6 of the gear segments and which is connected loosely at its rear ends with the transverserod 7 by lifting plates 23. 24 represents two shifting arms which are mounted loosely at their rear ends on the rock shaft 20 and which support at their other ends a transverse bar 25 which transverse bar is connected at its ends, by two links 26, with the lifting plates 23, whereby upon raising the lifting arms 24, the lifting bar 22 is causedto IEJJSQ .he gear segments and the other parts connected therewith resting on said bar. Upon depressing the transverse bar 25, the lifting bar 22 is moved downwardly and the gear segments resting thereon are permitted to move downwardly with the bar until the segments are arrested.

Eachof the gear segments is yieldingly held in contact with the lifting bar 22 by a spring 27 which connects the arm of the segment with the transverse bar 25. If the downward movement of the gear segment is arrested while the whifting arms 24 continue to move downwardly, the lifting bar 22 is moved away from the underside of the arm of the gear segment and the spring 27 is strained. The transverse bar 25 is arranged at one end in a segmental notch 28 formed in the front part of the rocking frame 15, as shown in Figures 2, 7, 9 and 19 and its opposite end is arranged in a similar segmental notch 28, formed in a rocking frame 29 (Fig. 19) which is secured to the operating shaft 20 on the left-hand side of the machine.

W'l1en the machine is at res; as shown in l 'igure 2, the transverse bar 25 engages with the front side of the notches 28 in the rocking frames 15 and 29. Upon turning the rocking shaft 20 forwardly by means of its handle 21 in the direction of the arrow, Figure 2, the rocking frames are moved forwardly during the first part of the movement independent of the transverse bar 25. The latter remains at rest until the inclined front end 16 of the cam 14 has raised the arm 13 and moved the gear segments into engagement with the dial pinions, during which movement the rocking frames move idly to the extent of their notches 28 along the ends of the bar 25 without disturbing the latter. After the gear segments have been engaged with the dial pinions, the continued forward movement of the rocking frames causes the rear ends of their notches 28 to engage with the bar 25 and depress the same, thereby causing the lifting bar 22 to be moved downwardly and strain the springs 27. This causes all of the segments which are free, to be moved downwardly and to continue their downward movement until they are arrested. During the downward movement of the gear segments, while they are in engagement with the dial pinions, the latter and the dials connected therewith are turned in the direction of the ar row, Figure 7, until the downward movement of the segments is arrested. The extent which each dial is turned depends upon the position in which the downward movement of its operating segment is arrested. After the segments have been arrested in their downward movement, they remain in this position while the rocking frames complete their forward movement. At the end of the forward movement of the rocking frames, the roller 18 of the rock arm 13 drops off from the rear end of the concentric part of the cam 14, thereby allowing the springs 11 to pull the gear seg-, ments rcarwardly out of engagement with the dial pinions.

Upon now turning the rock-shaft 20 backwardly by means of the handle 21, the rock ing frames are moved backwardly until the front ends of the notches engage with bar 25. When the latter is so engaged it is moved backwardly with the rocking frames to the end of their rearward movement which causes the transverse bar 25 to lift the lifting bar 22 and the gear segments which have been depressed, into their highest or normal position. During this upward movement of the depressed gear segments they are out of engagement with the dial inions, whereb the dials are not turned bacEwardly with the segments, but remain in their shifted position.

30 represents a number of elbow-shaped controlling arms. which form part of the devices whereby the downward movement of the registering gear segments is controlled. One of these arms is arranged along the lefthand side of each gear segment and consists of an upright front part and a horizontal lower part which extends rearwardly from the lower end of the upright part, thereby leaving a clear space in rear of the upright part of the controlling lever, as represented in Figures 1 2, 7, 9, 18, 30, 42, 43, and 47. The rear part of the lower end of each controlling arm is mounted loosely on a transverse supporting bar 31, while the upper end of its front or upright part is loose y connected with the upper portion of its companion gear segment. This loose connection permits the controlling arm and the gear segment to swing freely about their individual axes, which are arranged parallel but out of line, and also permits the gear segment to move forward and backward into and out of engagement with its companion dial pinion. In the uppermost position of the controlling arms the same bear with their upper ends against a transverse stop bar 32, as shown in Figure 2, which limits the upward movement of these arms. Each controlling arm is provided on the rear part of its upper end with a locking lug 33, and on the front part of its upper end with a stop lug 34, both of which lugs project toward the left and are preferably stamped out of one piece with the controlling arm.

The operation of the registering devices is controlled by a number of elbow-shaped key levers which are arranged side by side and pivoted to a transverse supporting rod 35. Each key lever is provided with a lower aetuating arm 36 which projects forwardly and an upper stop arm 37 which projects upwardly along the left hand side of one of the controlling arms' and gear segments, as represented in Figures 2, 7, 1 8, and 42. Each of these key-levers is provided on the rear side I is moved forward into engagement with the adjacent dial inion, and the rocking frames are turned orwardly for depressing 5 9 ing the segment. At the end of this forward the gear segment, the spring 27 of this segment will be strained without, however, shi

movement of the rocking segments, the roller 18 of the rock arm 13 drops off from the rear end of the cam 14 the gear segment is moved rearwardly out of engagement from the dial pinion and then the rocking frames move .backwardly without having shifted the dial.

The upper arm of each key lever is provided on its front side with a vertical series of differential sto shoulders 39, which are arranged step'fas ion and extend from the upper end of this arm downwardly and forwardly thereon, or in other words the stop shoulders are arranged radially out of line with one another and different distances from the pivot of the key lever. These stop shoulders of the key lever'are adapted tobe moved forwardly into the path of the stop lug 34, on the controlling 'arm. The stop shoulders are arranged different distances from the stop lug 34, of the controlling arm, so that by moving different stop shoulders of the key lever into the ath of thestop lug of the controlling arm, t e latter and the gear segment connected therewith may be arrested at different points in their downward movement. The uppermost stop shoulder of the key lever is most remote from thestop lug of the controlling arm and therefore requires the greatest forward movement of the key lever, in order to bring this stop shoulder into the path ofthis stop lug.

The stop shoulders of the key lever are so arranged that the distance from the stop shoulders to the path of the stop lug 34 gradually grows less from the uppermost stop shoulder to the lowermost stop shoulder. The

relative position of the diiferentstop shoul-' ders of the key lever is such that when its locking shoulder 38, remains in engagement with the locking lug 33, and the gear segment is simply moved into and out of engagement with its dial pinion, the latter remains at zero, if the same has not been previously moved. But when the key lever has beenmoved forwardly, so as to disengage its locking shoulder from the locking lug and moves one of its stop shoulders into thepath of the stop In of the controlling arm, the latter arm and gear segment connected therewith will be moved ownwardly, upon moving the rockmg frames forwardly, until the stop lug of the controlling arm strikes. the respective stop shoulder of the key lever which stands in 1ts path, as represented in Fi re 7 whereby the ear segment while turning in engagement with the adjacent dial gear pinion, turns the same forward. By turning the key lever forward more or less and moving one or the other of its stop shoulders into the path of the stop lu 34, of the controlling arm, the distance whic this arms descends can be varied, thereby varying the number of spaces which its gear segment turns the adjacent dial.

Main ml/mber key nwchaniem 40 represents the main keys whereby the key levers of the main registering and recordin mechanism are operated, and which are guided with their depending stems in the top 41 and bottom 42 of the key-board. As shown in the drawings, nine longitudinal columns of these ke s are arranged transversely side by side. T e first column on the right hand side of the machine contains seven keys and represents fractions of one-eighth of a cent, the next column toward the left contains nine ke s andrepresents cents and, the remaining co umns of keys toward the left each contains nine keys and represents progressively higher orders of numbers according to the decimal system, so that the registering keys in the last or left hand column represent hundreds of thousands of dollars.

The lowest numbers of the several columns of keys are arranged transversely in a row on the rear part of the key-board and the corresponding higher numbers of the several columns are arranged likewise in transverse rows and progressively in their order toward the front end of the key-board.

Each of the registering keys is yieldingly held in an elevated position by a spring 43 (Figs. 25 and 27) surrounding the stem of the key and connected at its upper end to the key and bearing with its lower end against the bottom of the key-board. The upper movement of each-key is limited by a shoulder 44 formed on the upper part of its stem and engaging with the underside of the top of the key-board, as represented in Figures 25, 27, 38, and 39;

The downward movement of all of the keys is substantially the same, but the arrangement of each column of keys lengthwise of the lower actuating arm of each key lever causes the keys to bear against the lever at different distances from its pivot so that by depressing different keys the same distance, the key lever will be turned different angular distances. The keys having the lowest numbers bear against their respective key levers nearest the pivot and consequently the levers are thereby thrown the greatest distance, and the uppermost stop shoulders are shifted into the path of the stop lug 34, of the respective controlling arms. The throw of each key lever upon depressing any one of its keys is so adjusted, that the proper stop shoulder on its upper arm is moved into the path of the stop lug 34, of the controlling arm and the downward movement of the respective gearsegment is arrested after having turned the adjacent dial gear pinion a number of spaces corresponding to the number of the key which is depressed.

Loose connection for segments The loose connection between each controlling arm and its gear segment, heretofore referred to, is shown in its simplest form in the connection between the controlling arm and the gear segment, which are controlled by the initial or lowest column of registering keys. As shown in Figures 1, 18, 30 and 43, the loose connection between the controlling arm and the gear segment of the lowest registering device consists of upper and lower guide lugs 45 and 46 arranged on the upper end of the segment and bearing a 'ainst the upper and lower guide faces 47 and 8, which are formed on the upper end of its companion controlling arm. As the controlling arm and segment rise and fall, the guide lugs of the segment slide back and forth on the guide faces of the arm. The guide faces are so constructed that the back and forth movement of the segment on the arm is radial with reference to the dial pinion in all positions of the segment. By. so forming the guide faces of the arm, the gear segment can be engaged with and' disengaged from the dial pinion in all positions of the segment without disturbing the position of the dial pinion. The construction of the loose connections between the controlling arms and gear segments of all of the higher registering devices above the fractional registering device, except the highest device are combined with carrying devices, whereby each registering dial, upon making one complete turn, causes the next higher dial to be turned forward one space, thereby carrying up a number from one order to the next higher order. The loose connections between the controlling arms and the segments and the carrying mechanism of the higher registering devices are constructed as follows As shown in Figures 1, 2, 7, 18 and 43, each controlling arm is provided at its upper end with upper and lower guide faces 47 and 48 and its lower guide face is engaged by a lower guide lug 46 on the adjacent gear segment, the same as in the coupling between the controlling arm and segment of the initial registering device. The gear segments of the higher registering devices are each provided with an upper guide lug 49 which is adapted at timesto bear against the upper guide face 47 of the companion controlling arm in substantially the same manner in which the upper guide lug 45 of the fractional gear segment bears against its companion arm, the only difference being that the upper guide lug 49 of the higher gear segments are held out of engagement and separated by a space from the upper guide face of the companion arm when no number is carried from a lower to a. higher registering device. The upper guide lug 49 is held in this elevated position above the adj acent guide face by a rocking latch 50 which is arranged in a notch in the rear side of the gear segment and which normally projects toward the left and engages with the upper guide face 47 of the adjacent controlling arm, as shown in Figures 2, 30 and 43.

During the ordinary up and down movement of each higher controlling arm and gear segment, the. latter is guided by its lower guide lug 46 and the locking latch 50 engaging with the lower and upper faces of the adjacent arm, this movement being the same as the movement of the controlling arm and gear segment of the fractional registering device. Normally the downward movement of the controlling arm is determined by the position of its companion key lever and this arm in turn controls the extent of the downward movement of the gear segment. When, however, the locking finger 50 is withdrawn out of engagement from the upper guide face 47 of the arm, the companion gear segment is capable of moving downward independently of the arm until the upper guide lug 49 engages with the upper guide face of the arm. The extent of this independent movement of the gear segment with reference to its companion arm is equal to one tooth or space of the segment, so that by this means the gear segment is enabled to turn the dial pinion one space more than the position of the key lever permits the same to move.

The withdrawal of the locking latch of each higher registering device .is controlled by the next lower registering device and the withdrawal of each latch is effected when the next lower registering device has made one complete turn and arrived at zero. Each of the locking latches is pivoted on the right hand side of its adjacent gear segment, so as to turn transversely with reference to the latter. The latch is turned toward the left into its operative position by a spring 51 (Fig. 10) the movement in this direction being limited by a shoulder 52 arranged on the latch and bearing against the right hand side of the gear segment, as shown in Figure 10. 53 is an upright trip plate connected wit the lower end of each latch and arranged upper end extends toward the left and normally at right angles or nearly so to the adjacent gear segment, when the latch is in its operatin position. 54 represents a number of upright trip arms, each of whichis controlled by a lower registering device and which turns the locking latch of the next higher registering device into an inoperative position. This arm is mounted loosely with its lower end on the supporting bar 35 and is provided at its upper end with a rearwardly and forwardly projecting hook 55, and in front and below said'hookwith a bend forming a bearing finger 56. 57 represents trip cams arranged on the left-hand side of each registering dialpinion and connected with the adjacent pinion and dial, but separated from the pinion by an intervening space or groove. The face of each of these cams begins at its lowermost point near the axis thereof and then extends outwardly in a spiral line terminating with its highest point radiall in line with its lowermost point with whic 1 it connects abruptly. The trip cam of the fractional registering device has its face divided into eight arts, each part of which is arranged one-eig th of a s ace further from the center of the cam than t e preceding part, while the trip cams'of the higher registering devices each has its face divided into ten parts, each part being arranged one-tenth of a space farther from the axis of the cam than the preceding part. Each of the trip arms 54 extends upwardly along the righthand side of the trip cam of a lower registering device and its shoulder 56 engages with the face of this cam, while the hook 55 at its is adapted to engage with the trip plate 53 of the next higher registering mechanism. In the initial position of each trip arm, its shoulder 56 engages with the lowest part of its trip cam, as represented in Figures 2 and 9. As the trip cam is turned in the direction of the arrow, Figure 2, at the same time that its dial and gearpinion are moved forwardly by the adjacent gear segment during the adding operation, the trip arm is moved backwardly by the gradually rising face of the trip cam. During this backward movement of the trip arm, its hook engages with the trip plate 53 of the next hi 'her registering device and is deflected toward the right thereby, the hook being sutficiently elastic for this purpose. After the hook has passed in rear of said trip plate, the hook owing to its resilience springs back to itsnormal position, so as to stand behind said trip plate. When the shoulder of the trip arm reaches the highestpart of the face on the trip cam the trip arm has been shifted to its rearmost position. Upon now turning this cam forwardly another space together with its companion dial and pinion, the highest part of the cam is carried from underneath the shoulder of 5 the trip arm and the latter is moved forwardly over the abrupt face of the cam until its shoulder 56 again engages with the lowest part of the cam face. Durin this movement of the trip arm, its hook stri es the rear side of the trip plate 53 of the next higher registering mechanism and turns the same forwardly, as shown in Figure 30, thereby disengaging the locking latch from the adjacent controlling arm and permitting the gear segment carrying the trip plate to move forward one space. The forward movement of the trip arm is effected when the dial with which its trip cam is connected has made one complete rotation and again stands at zero, whereby the addition represented by this complete rotation is carried to the next higher registering device. The forward movement of the trip arm is effected quickly by aspring 58, which connects with a stationary cross bar 59 arranged in front of the trip arms. The trip plate 53 of each registering device is so arranged and is of such length that the hook of the next lower trip arm can engage with the rear side of the plate, for disengaging its latch in any position of the gear segment carrying the plate. If a gear segment is locked in its highest position by reason of none of its companion keys having been depressed, the withdrawal of its latch from the controlling arm simply permits the gear segment to drop one space and turn its companion dial pinion forward one space, while in engagement therewith, the movement of this d1 al representing one number carried up from the next lower dial. If any one of the keys of the key levers has been depressed, so

as to release the gear segment and permit the same to move downwardly for effecting an addition, and if during this time the next lower registering device has made a complete turn, so as to require the carrying up of a number'from the next lower registering mechani'sm, the latch of the higher registering device will be withdrawn while the same is efi'ecting its addition, thereby causing the segment to descend and turn its dial one space in addition to the spaces corresponding to the lcpression of its respective key.

When the locking latch has been withdrawn so as to permit a gear segment to, move downwardly one space farther than its controlling arm, the latch remains in this position during the subsequent upward movement of the arm and the segment until the upward movement of the arm is arrested by striking the stop bar 32 and the gear segment continues its upward movement independent of the arm the extent of one space. The gear segment has now reached its highest position and its latch is again swung automatically by its spring over the controlling arm. The controlling arm and gear segment now remain in this relative position until another number is to be carried up from the next lower registering de- Vice.

When the controlling arm has been retract-- ed to its highest position, the adjacent key lever is moved into its normal retracted position, so that its locking shoulder 38 engages with the locking lug 33 of the controlling arm and locks the latter against downward movement. The return movement of such key lever is preferably effected by a spring 60 which connects the upper arm of the key lever with the transverse shaft 9, as shown in F igures 2 and 7, or some other convenient part of the machine. The lower guide lug 46 on the gear segment compels the arm to rise with the gear segment and avoids displacement of these parts with reference toeach other, and also serves as a stop to limit the upward movement of the gear segment.

The gear pinion and the co-operating gear segment of the fractional registering device are so constructed that the fractional dial makes one rotation whenever it is moved forward eight spaces. After the fractional dial has made one rotation the whole number represented by this rotation is transferred by the first carrying device from the registering mechanism of the fractional dials to the next higher registering device which represents cents. The complete turns of each of the following registering devices are in like manner carried or transferred to the next higher dial by the respective carrying device. The dial which records the highest number, in this instance the millions, is preferably operated only by the adjacent carrying device of the next lower dial and is incapable of being operated directly from the key-board because it is not provided with a key operating mecha nism. The mechanism whereby the dials 2 are all turned back to zero or the place of beginning after the addition of numbers has been completed is constructed as follows:

61 (Figs. 2 and 7) represents a series of feeling rock levers which are adapted to shift the key levers, so as to permit the gear segments to descend the proper distance for resetting or restoring the main registering dals to zero. One of these shifting levers is mounted loosely on the supporting bar 35 adjacent to the left hand side of each of the key levers and is provided on its upper arm with a forwardly projecting feeling finger 62 and with a shifting finger 63 which extends behind the upper arm of the adjacent key lever. The feeling levers have the r fingers normally arranged in rear of the cams 57 and each of these levers is turned so that its upper arm moves backwardly by the upper arm of the adjacent key lever engaging with the shifting finger 6'3 of the feeling lever. 64 represents a transverse pull bar arranged in rear of the lower arms of the feeling levers and connected with each of the latter by a pull spring 65, as represented in Figures 2, 7 and 19. This pull bar is connected at its ends to the lower end of two depending pull or rock arms 66, which are secured at their upper ends to the rock shaft 9, as shown in Figure 19. Upon turning this rock-shaft, so as to swing its depending pull arms backwardly the feeling levers are turned by means of the springs 65 so as to move the upper arms of these levers forwardly. This movement of the rock-shaft 9 is effected by a cam 67 (Figs. 14, 21 and 35), which is mounted on the left-hand side of the rocking frame 29 and which is constructed substantially the same as the cam 14 which is mounted on the rocking frame 15. As shown in Figures 14 and 21, this cam is pivoted at its rear end by a transverse pin to the rear portion of the rocking frame 29 and is provided at its front end with an incline or cam face 69-, and in rear of the incline with a concentric face 68. The cam 67 can be raised and lowered with its front end into an inoperative or operative position, this movement being limited by means of a lug 70 arranged on the cam as shown in Figure 19, and projecting into a slot 71 in the adjacent rocking frame in the same manner in which the movement of the cam 14 is limited, as shown in Figure 36.

72, Figures 14 and 19, represents a rearwardly projecting rock-arm secured to the rock shaft 9 and provided at its rear end with a roller or projection 73 which is adapted to be engaged by the cam 67 for turning the rock shaft 9. When numbers are being added with the machine, the cam 14 is depressed, as shown in full lines, Figure 2, so as to be in a position when moved forwardly by the rocking frame 15 to engage the roller on the arm 13, for moving the gear segments into engagement with the dial pinions, and during this time the cam 67 is lifted into the position shown in full lines, Figure 14, so that when the rocking frame 29 is moved forwardly, the cam 67 will clear the roller 73 of the rock arm 72 and not disturb the roellr1 shaft 9 and the parts connected therewit If it is desired to restore all of the dials 2 to zero, the cam 14 is raised into its inoperative position, shown by dotted lines 14 in Figure 2, and the cam 67 is lowered into its operative position, as shown by dotted lines 67* in Figure 14. Upon now turning the rock-shaft 20 by hand so as to move both rocking frames 15 and 29 forwardly, the cam 14 passes over the roller 18 of the arm 13 without disturbing the Same, but the inclined front of the cam 67 engages with the roller 73 on the rear end of the rock-arm 72 and raises the same until this roller engages with the concentric part 69 of this cam. By this movement of the arm 72, the rock shaft 9 is turned in the direction for moving its depending arms 66 rearwardly and pulling the springs 65 rearwardly. This pull on the springs 65 er parts of the trip cam are iguana causes the feeling levers to be turned until the feeling fingers of their upper arms engafge with the spiral surfaces of the trip cams. A er the feeling fingersbear against these cams, their movement is arrested and the continued backward movement of the pull bar 64 simply stretches the springs 65 until the bar reaches the end of its backward movement. The feeling finger of each feeling lever engages with that part of the surface of the ad acent trip cam which is directly opposite the feeling finger, and as these trip cams are turned with the adjacent dials they present different parts of their spiral surfaces to the opposing feeling fingers, which causes the forward movement of the upper arms of the feeling levers to be arrested in different positions when swung, forwardly. During the forward movement of the upper arm of each feeling lever, its shifting finger 63 engages with the rear side of the upwardly projecting arm of the adjacent key lever and moves this arm forwardly. The construction of the parts is such that the spiral surfaces of the trip cam bears a definite relation to the step-shaped series of stop shoulders on the upper arm of the key lever. When the feeling finger of the feeling lever, upon being moved forwardly, bears against the lowest part of the adjacent trip cam, the adjacent key lever is carried simultaneously forward with the feeling lever the greatest distance and its uppermost stop shoulder is carried into the path of the stop lug of the controlling arm. The succeeding parts of the spiralsurface of the trip cam are so constructed that they rise progressively higher and arrest the forward movement of the feeling lever when the same has carried the adjacent key lever with its corresponding stop shoulder into the path of the stop lug of the controlling arm. This forward movement of the feeling lever and that of the upper arm of the key lever is gradually reduced as the progressively highpresented to the feeling finger, and when the highest part of the trip cam is presented to the feeling finger, the feeling lever is prevented from moving forward at all and the upper arm of the key lever is not moved with its locking shoulder out of engagement with the locking stop of the controlling arm and consequently the companion gear segment connected therewith is held against downward movement. After the rocking frames 15 and 29 have been turned forwardly sufiiciently to engage the several feeling fingers of the feeling levers with their respective trip cams, the rear ends of the segmental notches 28 in the rocking frames engage with the cross bar 25 and depress the same, thereby moving the lifting bar 22 downwardly and at the same time ulling down the springs 27. This downward pull on these springs causes 65 each spring to pull'its respective gear segment down as far as possible, and after the downward movement of the segment has been arrested the continued downward movement of the cross bar 22 together with the rocking frames simply stretches these springs until the bar reaches the end of its downward movement. If a gear segment is locked in its uppermost or zero position its spring 27 will be stretched its fullest extent, whereas, if a gear segment moves downwardly more or' less before it is arrested by its shifted key lever, its spring 27 will be stretched less in proportion. This downward movement of the gear segments, which are free to move in this direction takes place while the gear segments are in their retracted position and out of engagement from the dial pinions, 'so that the dials are not affected by this movement of the segments. After the rocking frames have reached the end of their forward movement and the roller 73 has dropped off from the rear end of the concentric portion 69 of the cam 67, the gear segments are moved forwardly by hand operated mechanism into engagementwith their respective dial pinions and are held in this position during the en-- tire subsequent backward movement of the rocking frames, which is effected by hand operated mechanism. During the backward movement of the rocking frames, the gear segments are raised to their highest positions,

while in engagement with the dial pinions by the rod 22 and connecting parts and turn the dials backwardly. At the end of the upward movement of the gear segments the latter are released, so as to permit them to move into their retracted position, out of engage.- ment from the dial pinions.

During this operation, those gear segments which are held or locked in their highest positions, by reason of their dials being at zero, are simply moved forward at the end of the forward movement of the rocking frames, so as to engage with their respective dial pinions and are again moved backwardly out of engagement therefrom at the end of the backward movement of the rocking frames, without disturbing their respective dials. Each of the unlocked gear segments is moved downwardly a number of spaces correspondingto the number which its dial backward the same number of spaces that the gear segment was depressed. Inasmuch as each gear segment was permitted
